补充:suggest(ion)等后用虚拟语气的情况:我们表示“建议”“要求”“命令”“应当做……”这一意义时,suggest等动词后的宾语从句中的谓语常用"(should+) 动词原形”;这类动词的字头记忆口诀是:I DROP CAPS,具体为:insist坚持;demand要求,desire要求,请求;request请求,require需要;要求;order命令;propose建议;command命令;ask要求;advise建议;prefer宁愿;suggest建议 (1) 这些动词变被动语态 (如:It is suggested + that主语从句)形式后,主语从句谓语动词仍用“(should+)动词原形”。 (2) 这些动词变名词(如:suggestion)后,其后的表语从句和同位语从句中的谓语部分仍用“(should+)动词原形。” (3) 此类动词不表达“某事必须或很重要”这一意义时,宾语从句中不用虚拟语气。She insisted that she heard somebody in the house. 她坚持说她听到房子里有人。Her expression suggested she was angry. 她的表情表明她很生气。 2) allow (1) v. 允许,准许 They do not allow smoking here. 他们不允许在这里抽烟。They allowed her to go to the party. 他们允许她去参加聚会。(2) v. 给予,提供(钱或时间) He allows his son ten dollars a month. 他每月给儿子10元钱。Your gift allows me to buy a car. 你的赠礼使我能够买一辆车了。The facts allow no other explanation. 这些事实不容易做解释。 辨析:allow,permit与let: (1) allow和permit都表示“允许”,用法也一样,在许多情况下可以互相换用,只是词义的强弱上有些差别。(2) allow词义较弱,含有“听任”“默许”“不加阻止”的意思。permit词义较强,强调“正式认可”“批准”的意思。let表示“让”,词义最弱,较口语化,用法上也不同于allow和permit;在let后面的宾补为不带to的动词不定式;let一般不能用被动语态。That teacher allows too much noise in the classroom. 那位老师听任教室里大声吵闹。Schools do not permit smoking. 学校不准吸烟。The nurse allowed him to remain there, though it was not permitted. 护士让他留在那里,虽然这是(规定)不允许的。Let me help you. 让我帮你吧。 8. … and it is believed to be caused by a sea monster. 人们认为这是由于一种海中怪兽造成的。(P. 11 第二段第2行) cause: (1) v. 导致;成为……的原因;使发生He often causes trouble to / for people. 他常给人们惹麻烦。His illness caused him to miss the game. 他因病不能参加比赛。 (2) n.
